Arthroplasty as Primary Treatment for Metadiaphyseal Proximal Humerus Fractures: A Viable Alternative to Osteosynthesis for the Elderly.

Introduction: in the elderly patient population, where fracture comminution, osteoporotic fractures, and associated arthritis or rotator cuff pathologies dominate, metadiaphyseal proximal humeral fracture is a challenging subset of fractures to treat. This study reports on cementless long-stem reverse total shoulder arthroplasty (RTSA) as primary treatment of metadiaphyseal proximal humeral fractures in elderly patients.

Materials & Methods: Between January 2018 and October 2021, 22 consecutive patients sustained proximal humerus fractures with metadiaphyseal extension and underwent surgery with cementless long-stem RTSA.

The Effect of Resident Involvement in Hip Fracture Surgery: An Analysis of a Single Institution Before and After the Addition of an Orthopaedic Surgical Residency.

Introduction: Hip fractures are common injuries that are associated with serious morbidity/mortality in the elderly and represent a substantial financial burden to healthcare systems. Previous studies demonstrated that resident involvement in orthopaedic surgeries is associated with increased surgical time and cost, with equivocal or worse outcomes. This study evaluated outcomes of hip fracture surgery at one institution, before and after the introduction of an orthopaedic residency program.

Digital Papillary Adenocarcinoma in the Dorsal Proximal Ring Finger.

Digital papillary adenocarcinoma (DPA) is a rare and aggressive tumor arising from the eccrine sweat glands. It is found on the hands and feet and most commonly occurs on the volar and distal finger tips. In this report, we describe a DPA in a 45-year-old woman who presented with a slowly enlarging mass on the dorsal aspect of her proximal ring finger.

Anteroinferior Hip Instability in Flexion During Dynamic Arthroscopic Examination Is Associated With Abnormal Anterior Acetabular Horn.

Background: The stabilization of the femoral head is provided by the distal acetabulum when the hip is in a flexed position. However, the osseous parameters for the diagnosis of hip instability in flexion are not defined.

Purpose/hypothesis: To determine whether the osseous parameters of the distal acetabulum are different in hips demonstrating anteroinferior subluxation in flexion under dynamic arthroscopic examination, compared with individuals without hip symptoms.
